Specification of Letters Patent.

Patented Aug. 6, 1912.

sight having a fixed point of elevation incapable of adjustment and known as a battle-sight. It is usual though not universal to so adjust the elevation of a battle sight with relation to the capabilitiesof the rifle as to give a trajectory to the bullet, the vertax of which shall not exceed in height the height of the objective against which such ritle is commonly employed. But in war, the objectives of the battlefield, usually men, are well known to alternately adopt two positions. When, for example, a man stands erect his height is from three to four times greater than when he is lying prone. If,

therefore, a battle sight having a single fixed point of elevation adapted to give a trajectory not exceeding the height of a man in the prone position be employed, then the range within which the rifle would be effective against an erect figure is unduly shortened. If, on the other hand, the single fixed point of elevation is adapted to an erect figure, then the distance within which a prone figure is vulnerable is unduly limited. B

My object, therefore, is to produce a backsight more particularly adapted to battle which shall provide two definite points-,of elevation, so constructed as to admit of change from one to the other by such simple definite movements as to preclude the possibility of mistake.

With these and other objects in view I have devised the novel gun sight which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is a rear elevation of one form of the invention; Fig. 2 a section on the line 2--2 in Fig. 1; Fig. 3 a rear elevation of a second fo m of the invention; Fig. 4 a side elevation corresponding with Fig. 3; Fig. 5 a rear elevation of a third form of the invention; Fig. 6 a side elevation, partly in vertical section, corresponding with Fig. 5; and Fig. 7 is a section on the line 7-7 in Fig. 5 looking in the direction of the arrows.

p The essential feature of the invention con sists of two superposed members, which are preferably hinged to the gun so as to fold down out of the way when not in use, one of said members being movable relatively to the other member, which I will term for convenience the fixed member, and one or both of said members being provided with apertures and the movable member, Whether or not it is provided with an aperture or apertures, co-acting with an aperture or apertures in the fixed member to produce two definite points of elevation or sight lines. As a convenient means of attaching the sightto the gun I have shown a yoke or carrier 10, the base of which is provided with screw holes for attachment in place. To this yoke is hinged a plate 11 which for the purposes of this specification is termed the fixed member and is provided with an aperture or apertures, z'. e. a vertical slot or a plurality of holes.

In the form illustrated in Figs. 1 and 2. the movable member is a swinging plate 24 which is pivoted to plate 11 as at 95. The pivot screw is tightened up sufficiently to hold the swinging plate in any position in which it is placed, its movement in either direction being limited by stop pins 26. The indicating handle for convenience is placed at the top of the plate and projects slightly above the top of plate 11. The swinging plate is provided with an upper aperture 27 and a lower/ aperture 28, not in vertical alinement, either of which is adapted to be placed in coincidence with an aperture in plate 11 but both cannot be simultaneously in coincidence therewith. When the swinging plate is in position to place the lower aperture in coincidence with the slot, for example-when swung toward the right as in Fig. 1, the sight will be adjusted to shoot at a man in the prone position. By swinging the plate toward the left from the position shown in Fig. 1, the upper aperture ment and a plate 31 is pivoted to swing vertically instead of horizontally, its movements being limited by stop lugs 30. The swinging plate in this form has no apertures and is made wide enough so that both aper tures in plate ll can not be exposed simultaneously. The operation is the same as before.

In the form illustrated in Figs. 5, 6 and 7, plate 11 is provided with holes 29 in vertical alinement as before and is also provided with a transverse recess 32 which receives a slide 33, the ends of which are curved about plate 11. This slide has no apertures and is made wide enough so that both holes in plate 11 cannot be exposed simultaneously. In this form, the same result is accomplished by moving the slide upward and downward to the extremes of its movement that is accomplished by swinging plate3l in the form last described, the top and bottom walls of recess 32 serving as stops to limit the movement of the slide.

It will be noted that in all the forms one sight line is always obscured and the adjustment mustbe to one of the definite points of elevation described.

Having thus described my invention I claim:

1. A battle sight comprising fixed and movable members, said fixed member being provided with an aperture or apertures and said movable member being adapted to cooperate therewith to produce two sight lines, one of which is always obscured, and stops for ositively retaining the movable memher in position to open one sight line and obscure the other.

2. A battle sight comprising iixed and movable members, said fixed m mber being provided with two apertures and said movable member being adapted to obscure one aperture leaving the other exposed, whereby two sight lines are provided, and stops engaged by the movable member at either extreme of its movement.

3. A battle sight comprising nxed and movable members, said fixed member being provided with two apertures and a transverse recess which receives the movable member, the top and bottom walls of said recess acting to stop the'movable member at the extremes of its movement, leaving one sight line open and the other obscured.

4. A battle sight comprising a fixed member having two apertures and a transverse recess and a slide in said recess adapted to obscure one of said apertures leaving the other open, for the purpose set forth, the 'top and bottom walls of the recess serving as stops to limit the movements of the slide.

In testimony whereof I afiix my signature in presence of two witnesses.
